Proofpoint is looking for a talented, self-driven individual to play a major role developing our next generation Threat Protection services that focus on detecting, blocking, and tracking highly-sophisticated spam and malware attacks against enterprise organizations.

Stopping these kinds of attacks is no small feat, you literally have to be able to find needles within oceans of needles – which our Targeted Attack Protection product does. This product has been selling extremely well and Proofpoint’s leadership in this market is being recognized by analysts and, more importantly, our customers.
